I started as a Ph.D. Student with Dr. Arroyave’s Group in Fall 2017, and have been working on the computational design of steel materials using thermodynamics and information-fusion techniques. Side projects have extended into the use of machine learning techniques for quantification of microstructures.
Before Starting my Ph.D. I worked in materials research and development at Mintek in South Africa. Some of my focus areas while working there was the development of more corrosion and oxidation resistant FeAl alloys, colored gold and platinum jewelry alloys and metal spray forming.

I am from Iran and currently a Ph.D. candidate of Materials Science & Engineering at Texas A&M University. I received a bachelor’s degree from Sharif University of Technology (SUT), and subsequently a master’s degree from Khaje Nasir Toosi University of Technology (KNTU). I am proud to declare that I was recognized as a top graduate student among the graduates of academic year of 2008-2009, and honored for obtaining the highest total GPA.
Because of my intense enthusiasm for investigating in different fields of materials science, I did various experimental and theoretical research during my past education, including “assessment of surface resistance in polymeric nano-composite materials”, “evaluation of hot deformation behavior in steels and titanium alloys, “synthesis, characterization, and microscopic analysis of different types of nano-materials”, etc, which led to the publication of different ISI and conference papers.
I joined Prof. Arroyave’s group in Fall 2014, and my research field of interest is alloy design under uncertainty, including modeling and Bayesian uncertainty analysis of plastic flow behavior of low-alloy TRIP-assisted steels, and precipitation kinetics of NiTi based shape memory alloys.

Tanner Kirk is a Ph.D. student in the Mechanical Engineering Department at Texas A&M University. He is co-advised by Dr. Richard Malak and Dr. Raymundo Arroyave. Tanner researches the use of robotic path planning algorithms to design Functionally Graded Materials (FGMs). The methods Tanner develops use thermodynamic predictions of phase formation (CALPHAD) to plan FGMs that avoid the deleterious phases that often plague the manufacturing of FGMs. These methods are scalable to FGMs composed of an arbitrary number of elements and can be used to optimize FGMs for performance. Tanner’s other research interests are machine learning, optimization, and materials design.
Elias J Muñoz
Graduate Researcher
Arroyave Group, Texas A&M University
Topics:
– Micro-structure evolution of silicon carbides and other ceramic matrix composites (CMCs)
– Accelerated materials discovery using data-simulated-enabled framework
– Database creation and management of binary and ternary thermodynamic assessments
Current Work:
– Using an informatics-based approach, I look to discover new candidates for intermetallic melt infiltrants with optimal melting ranges and compatibilities with SiC and develop thermodynamic-based methods to discover alloy and process conditions for processing defect-free SiC/SiC composites by melt infiltration.
– Following that, we will then validate and demonstrate infiltrants through rapid infiltration methods.

Meelad Ranaiefar received his B.S. in Mechanical Engineering from Texas A&M and is now pursuing a Ph.D in Materials Science and Engineering. His current work involves modeling the contributing effect of differential evaporation on an additively manufactured part, consisting of nickel, titanium, niobium, or aluminum material. This is because differential evaporation can be seen as a negative side effect in the additive manufacturing process, leading to undesired changes in the microstructure of a material, but, through modeling and greater understanding, it can be used to control location specific microstructure and properties in materials.
Research Interests:
- Additive Manufacturing
- Welding

(a) Calculated elastochemical miscibility gap versus the chemical gap showing the shift of the miscibility gap and spinodal lines due to the strain energy impact. Experimental data are taken from the literature. The parameters used in calculation of the elastochemical miscibility gap are summarized in Table 2. (b) Enthalpy of formation. (c) Total elastochemical energy curves versus chemical energies at 420 °C, 520 °C, 620 °C, 720 °C, and 820 °C. (d) The three-dimensional strain–composition–temperature phase diagram for the Mg2Si–Mg2Sn pseudo-binary system. The red and green lines are elastochemical miscibility lines whereas the blue lines are chemical miscibility lines. For comparison, the miscibility gap from Kozlov et al. is plotted.
