Alexander Goldman, Ph.D.
I invent materials and build the means to make them.
- 01A magnesium alloy family with a filed patent application.
- 02Open source software that metallurgists use.
- 03A laboratory built from an empty room.
I am looking for conversations with founders, investors and operators in materials, manufacturing and hard technology.

What I do
I hold a Ph.D. in Industrial Engineering from Iowa State University, and a bachelor's in materials science and engineering from the University of Nevada, Reno. My doctoral work produced a rare-earth-free magnesium alloy family: I designed the compositions, cast and extruded them, heat treated them, and then found out through mechanical testing and electron microscopy why one composition was both stronger and more ductile than the last. A patent application on that family is filed.
The work runs end to end, which is the part that matters commercially. I have built a micro-industrial laboratory from an empty room: vacuum induction furnace, wire EDM, three-axis CNC, lathe, electropolishing and electron microscopy. I am usually the first in a group to learn a technique, and then I write the procedure down and train everyone else on it. I host tours of our shared additive laboratory for visitors of every technical background, which is where the metallurgy has to be explained rather than measured.
I am a chronic problem solver, which mostly means I do not stop at the behaviour. I stop at the cause.
I am now moving that work toward commercialisation, and I take part in the startup community in central Iowa. If you are building something where materials or manufacturing decide whether it works, that is the conversation I want.
Selected projects
Rare-earth-free Mg-Al-Bi alloys
2023 to 2026A magnesium alloy family that gains strength and ductility at the same time, which those two properties usually refuse to do together. Bismuth suppresses the Mg17Al12 precipitate and aluminium suppresses twinning; the combination is what buys both. Designed, cast, extruded, heat treated and tested in our own laboratory, then published in Materials Science and Engineering: A.
ptm-ipf
2026, open sourceAtomistic simulations produce millions of atoms and no picture a metallurgist can read. ptm-ipf turns them into the pictures we already know how to read: EBSD-style inverse pole figure maps, pole figures and orientation densities, in the same EDAX and TSL colour key an EBSD detector would give, verified against orix to 2 parts in 100,000. It has a command line, a local web interface and tests that run on Linux, Windows and macOS.
Multiscale digital twin for metal additive manufacturing
in progressA simulation stack for wire and powder directed energy deposition on a robot arm, and for laser powder bed fusion, intended to run beside the real machine rather than after it: machine data feeds the simulation, and the simulation feeds back process parameters worth trying.
A micro-industrial laboratory
2023 to 2026Specified, installed and now operate the equipment an alloy study needs from beginning to end: vacuum induction melting, wire EDM, three-axis CNC milling, metal lathe, heat treatment, electropolishing, and sample preparation for electron microscopy. Written procedures for each, and the training that goes with them.

Experience
Research Assistant, Iowa State University
2023 to 2026- Ran a full material qualification study: alloy design, vacuum induction casting, extrusion, heat treatment, mechanical testing and microstructural characterization.
- Designed heat treatments to control intermetallic precipitate morphology, and measured what each one did to the mechanical response.
- Designed and analysed structured experiments to connect process to microstructure to properties, with the statistics done in Python.
- Built and operate the laboratory the work runs in.
