Abstract: One or more embodiments relates to a high-temperature, titanium alloyed, 9 Cr-1 Mo steel exhibiting improved creep strength and oxidation resistance at service temperatures up to 650° C. The 9 Cr-1 Mo steel has a tempered martensite microstructure and is comprised of both large (0.5-3 ?m) primary titanium carbides and small (5-50 nm) secondary titanium carbides in a ratio of. from about 1:1.5 to about 1.5:1. The 9 Cr-1 Mo steel may be fabricated using exemplary austenizing, rapid cooling, and tempering steps without subsequent hot working requirements. The 9 Cr-1 Mo steel exhibits improvements in total mass gain, yield strength, and time-to-rupture over ASTM P91 and ASTM P92 at the temperature and time conditions examined.

Abstract: The invention relates to a composition and heat treatment for a high-temperature, titanium alloyed, 9 Cr-1 Mo steel exhibiting improved creep strength and oxidation resistance at service temperatures up to 650° C. The novel combination of composition and heat treatment produces a heat treated material containing both large primary titanium carbides and small secondary titanium carbides. The primary titanium carbides contribute to creep strength while the secondary titanium carbides act to maintain a higher level of chromium in the finished steel for increased oxidation resistance, and strengthen the steel by impeding the movement of dislocations through the crystal structure. The heat treated material provides improved performance at comparable cost to commonly used high-temperature steels such as ASTM P91 and ASTM P92, and requires heat treatment consisting solely of austenization, rapid cooling, tempering, and final cooling, avoiding the need for any hot-working in the austenite temperature range.

Abstract: A method of processing a semiconductor substrate is provided. The method includes depositing an amorphous hydrogenated carbon film on a semiconductor substrate using a low temperature plasma deposition process and performing at least one high temperature processing step on the semiconductor substrate. The SiC substrate is processed by ion implanting at least one dopant species into at least one selected region of the SiC substrate, depositing a amorphous hydrogenated carbon film on the SiC substrate using a plasma enhanced chemical vapor deposition (PECVD) process, performing at least one high temperature processing step on the SiC substrate and removing the amorphous hydrogenated carbon film after performing the high temperature processing step.
