Web4 de out. de 2024 · In addition, polymer forming is a rapid cooling process, and the cooling rate (dT/dt) has a significant effect on the pvT behavior of polymers. However, today’s commercial testing devices cannot obtain the pvT data for high cooling rates. Hence, the prediction of specific volume of polymers for rapid cooling applications remains a … WebAustenite, also known as gamma-phase iron (γ-Fe), is a metallic, non-magnetic allotrope of iron or a solid solution of iron with an alloying element. In plain-carbon steel, austenite exists above the critical eutectoid temperature of 1000 K (727 °C); other alloys of steel have different eutectoid temperatures. The austenite allotrope is named after Sir William …
