The high-temperature metallurgy of advanced borated stainless steels has been evaluated through differential thermal analysis, aging studies, quantitative metallography, and impact toughness measurements. Differential thermal analysis (DTA) was condu

The hydrogen embrittlement (HE) susceptibility of precipitation age hardened stainless steels (17-4 PH, PH 15-5, PH 13-8 Mo, and others) is well established in the literature. Susceptibility is a strong function of strength and hence lower aging temp

The microstructure of investment cast PH 13-8 Mo stainless steel heat-treated to various conditions was studied using light and electron microscopy, electron probe microanalysis, and Mossbauer spectroscopy. The mechanical properties were investigated

The hardening response of investment cast PH 13-8 Mo stainless steel has been evaluated by hardness measurements following aging in the temperature range normally specified for this alloy (510 °C to 593 °C). A new relationship between fraction tran

We compare the hydrogen-assisted cracking resistance of wrought PH 13-8 Mo stainless steel alloyed with 0.4 to 1.0 wt pct palladium to the conventional alloy when aged to yield strengths of 1170 to 1250 MPa. Intergranular hydrogen cracking is suppres

Differential thermal analysis (DTA), high-temperature water-quench (WQ) experiments, and optical and electron microscopy were used to establish the near-solidus and solidification microstructures in PH 13-8 Mo. On heating at a rate of 0. 33 °C/s, th

The possible microstructures resulting from both fusion and solid-state processing of Ti-26Al-11Nb at. pct (Ti-15Al-21Nb wt pct) have been determined. The particular microstructure produced was primarily a function of the cooling rate from theβ solv

The solidification behavior of two commercial aerospace superalloys, INCOLOY 909 and INCONEL 718, has been examined. Specifically, differential thermal analysis (DTA) revealed that INCOLOY 909 terminates solidification with the formation of a single
