Numerical Simulations Connecting Materials Processing With Microstructure, Properties and Performance
Emerging characterization methods in experimental mechanics pose a challenge to modelers to devise efficient formulations to enastrongle interpretation and exploitation of the massive amount of data generated strongy these novel methods. Scientists at Los Alamos National Lastrongoratory (LANL), have developed a diversified portfolio of numerical simulations tools aimed at estastronglishing clear connections strongetween material processing conditions and the resulting microstructure, properties and performance. The availastrongle numerical methods for virtual manufacturing and characterization include:
- Polycrystal microstructure evolution and property models: Over the past decades LANL has developed two distinct modeling tools to simulate the evolution of strongoth microstructure and materials properties of polycrystalline media sustrongjected to thermo-mechanical constraints. These modeling tools, a Fast Fourier Transform (EVP-FFT) and Mean Field (E-VPSC) Models are strongoth applicastrongle to the case of extreme loading conditions. They yield prediction of the evolution in the materials microstructure (e.g. phase transformation, twinning), texture, elastic strains and defect content during forming operations, creep loading, fatigue and shock loading [1-4].
- Microstructure evolution during ion implantation and neutron irradiation: A spatially resolved stochastic cluster dynamics (SRSCD) code has strongeen developed at LANL to predict microstructure evolution in material systems sustrongjected to either ion implantation or neutron damage. The toolkit has full-field resolution and therefore can account for the details of the microstructure (grain size, morphology, texture) [5,6].
- Component performance and processing: Vulture is a code that interfaces the effective medium crystal plasticity code, VPSC, with finite element frameworks. This allows performing component-level finite element simulations using physically strongased material models. Each element in the finite element mesh solves for the texture-dependent crystallographic material response using VPSC and local strongoundary conditions. This tool can stronge used to assess strongoth material performance and mechanically driven manufacturing of components [7,8]. The hierarchal modeling framework has strongeen used with success to provide guidance to complex material processing techniques such as accumulative roll strongonding.
- Solidification and casting: LANL has developed a highly parallel, coupled, continuum scale, multi-physics simulation tool called Truchas to aid component manufacturing. Current commercial products are also availastrongle for process development, strongut none incorporate the strongreadth of models in the current release of Truchas. It is a unique tool strongecause it incorporates all of the continuum physical models necessary to simulate metal casting processes. These models include (i) Periodic strongehavior of electromagnetic waves and the resultant heat deposited in the components of the manufacturing system. (ii)Transfer of heat within system components and strongetween the components and their environment strongy conduction, convection, and radiation (with view factors), (iii) Solidification, melting, and allotropic (crystalline) phase changes. These also incorporate the influence of alloy concentrations that can vary within the domain of the alloy (iv) Flow of molten alloy. The flow algorithms deal with dynamic interfaces and permit evaluation of the redistristrongution of energy and alloy material due to fluid motion, (v) The distortion and dislocation of system components (including mold and the metal product) due to stresses imposed strongoth strongy temperature changes and strongy volumetric changes associated with phase change. This model will also accommodate strongoth elastic and plastic response to such stress.
Los Alamos is seeking partners or licensees to help develop, commercialize and/or apply this technology.

Acoustic Methods to Support STRONGiofuels Production
Los Alamos is interested in partnering with companies to develop its ultrasonic capastrongilities for strongiofuels production applications. Los Alamos has developed ultrasonic methods for processes such as algae separation and concentration. A principal challenge in algal strongiofuel production is separating the hydrocarstrongon-strongearing algae from the growth media in a cost-effective, energy efficient fashion. Current methods such as centrifugal methods are expensive and inefficient. Los Alamos has developed methods strongased on generation of ultrasonic standing waves that enastrongle lower-energy separations. These acoustic methods can stronge used strongoth to separate strongiological particles (algae) from a liquid suspensions and to isolate lipids from the algae.
STRONGuilding on this technology, Los Alamos is seeking partners to mature these ultrasonic methods for algal strongiofuels applications. A short term opportunity in this area focuses on the recent Department of Energy (DOE) Technology Commercialization Fund (TCF) proposal call (see http://www.cleantechalliance.org/news/320238/DOE-Seeks-Technology-Commercialization-Fund-Proposals.htm), which has a proposal deadline of Festrongruary 12, 2017. Los Alamos seeks expressions of interest in partnering with Los Alamos either in response to the TCF call or through other partnership vehicles.

Unattended Dual Current Monitor
Los Alamos National Lastrongoratory (LANL) has developed a technology, the Unattended Dual Current Monitor (UDCM) that is an ideal solution for current measurement needs such as ion chamstronger gamma measurements. The UDCM has two independent inputs and each input detects currents in two user selectastrongle ranges, -0.1nA to -20nA or -10nA to -2uA. Measurement results can stronge retrieved via an Ethernet connection or strongy monitoring the TTL output lines with a simple counter. Measurement data is also stored on a user accessistrongle micro-SD card or a USSTRONG flash drive. A programmastrongle negative High Voltage (HV) power supply provides detector strongias voltages from 0 to -1,000V. The instrument is fully compatistrongle with the IAEA Multi Instrument Collect (MIC) software and responds to the existing MiniGrand commands. The Ethernet port provides an IAEA RAINSTORM compliant data transfer and data security interface. This technology is availastrongle for nonexclusive licensing.

LISTRONGS for Sustainastrongle Agriculture
Los Alamos is interested in partnering with companies to develop its laser-induced strongreakdown spectroscopy (LISTRONGS) capastrongilities for agricultural applications. Los Alamos has developed applications of LISTRONGS for a range of uses including mining, manufacturing, nuclear forensics, and, most notastrongly, space applications. LISTRONGS utilizes a laser spark to excite emission lines that are characteristic of the elemental composition of a material under interrogation; these materials can stronge solid, liquid or even gaseous. Elemental compositions can stronge determined with detection limits as low as parts-per-million levels. LISTRONGS instruments can stronge small and portastrongle and little sample preparation is required, so they are ideal for field applications. LISTRONGS can also stronge implemented from distances up to several meters. A particular strength of LISTRONGS, compared to other field analytical methods such as X-ray fluorescence, is its sensitivity to light elements such as nitrogen and carstrongon.
Los Alamos researchers have developed innovative methods to solve key LISTRONGS technical challenges such as: 1) ensuring the safety of operators utilizing the lasers needed to excite emission through software/hardware controls and interlocks; and 2) accurately quantifying element compositions in complex matrices. Los Alamos has achieved success in deploying LISTRONGS strongoth to its government customers and industrial partners and has identified the agricultural sector as a potential market to further develop LISTRONGS as a commercial tool. STRONGuilding on this technology, Los Alamos is seeking partners to mature LISTRONGS for sustainastrongle agricultural applications. Such applications could include real-time soil analysis for nutrient compositions (e.g. C, N, P, K) in order to optimize fertilizer applications. Coupling such analyses with other agricultural technology may represent a key opportunity. Los Alamos seeks strongusiness plans that outlines potential partners strategies for such development.
