A free, offline web toolkit for powder-metallurgy process design, from compaction density to cost-performance optimization.
Powder Metallurgy Lab is a single-page engineering assistant for the powder-metallurgy (PM) process chain. It covers compaction, sintering, net-shape mold compensation, structural FEM/CAE, secondary operations, robust process windows, quality and a one-click cross-tab report. Everything runs locally in your browser with no install, no account and no data upload. The descriptions below explain what each tab does.
Green density from compaction pressure (Heckel / Kawakita), sintering shrinkage and net-shape mold compensation; engineering mode adds the axial density gradient and inverse solving.
2D density field across the compact cross-section, plus a simplified die-stress & springback estimate.
Thermal cycle, liquid-phase sintering and dimensional tolerance band.
Import a 2D part profile (.dxf) and generate a PM process card with geometry, mass and mold compensation.
Linear-elastic tetrahedral FEM of a cylindrical compact under axial compaction. Colour = von Mises stress.
Real FE ejection: penalty wall contact + Coulomb friction, stepped stroke. Force–travel, von Mises field, cracking/scoring/stiction warnings.
Friction-decay pressure model (Amontons) predicts the compact density gradient and fill evolution. Teaching-grade — calibrate against real powder before production.
Linear-elastic FE stress of the sintered part under service load + static safety factor + Basquin fatigue life (PM fatigue ratio ≈0.35).
Sizing, surface densification, carburizing of FN steels, steam treatment — property modifiers (teaching-grade; calibrate before production).
Monte Carlo propagation of powder/pressure/friction variation; yield & sensitivity (teaching-grade).
Defect-risk prediction (delamination, ejection / corner cracking, warpage) and tolerance-chain SPC with Cpk and yield.
One-click cross-tab engineering report that aggregates every module's key results into a single A4 document (process cards + cost / quality / reliability summary), with PDF export.
All physics are teaching-to-engineering-grade approximations: Heckel / Kawakita compaction, mass-conservation sintering shrinkage, the Skorochod density–strength law, Lame thick-wall die stress validated against FEA, and Basquin fatigue. Material coefficients come from a built-in 20+ grade library (iron, stainless, copper, aluminium, titanium, hardmetal and more). Calibrate the coefficients with your own powder, press and furnace before production use.
Powder Metallurgy Lab is a single-page web app with zero external dependencies. Everything runs locally in your browser — no server, no account, no data upload. Download the folder and open index.html offline; this documentation page works the same way. The only network actions are the optional Home link and the email contact button.
