網頁2024年12月21日 · Low Temperature Toughness In general, higher strength and higher hardness means lower toughness. Therefore we would expect steel at low temperatures to have lower toughness than room temperature steel. This may be concerning if knives are to be used outdoors in the winter, particularly in northern climates. 網頁The properties of carbon and alloy steels are dependent on the relationships between chemical composition, processing, and microstructure. This article discusses the effects of alloying and residual elements on the mechanical properties of carbon and alloy steels.

網頁2024年3月21日 · Most steel is prone to crack at low temperatures. This is due to something called the brittle-ductile transition; a phenomenon that causes materials at low temperatures to shatter, rather than deform, on impact. 網頁A hydrogen environment causes embrittlement at ambient temperature [6] and low temperatures [7-9] down to 80 K under 1.1 MPa gaseous hydrogen. However, no tensile or fatigue data is available neither for the higher pressure hydrogen and low temperature
