Study on the Micro-Structure of High Temperature Oxide Scales Applied Loads on 12CrMoV Alloy

摘要

The 12CrMoV alloy steel is the most commonly used high pressure vessel and heat pipe using the material.This article on external forcing 12CrMoV alloy steel of high-temperature oxide layer for microscopic analysis of oxide layers of micro-cracks and exfoliation,oxidation layer portion of the oxide layer break,the oxide layer fold,multilayer structure oxide,oxidation and give the structure of the matrix and the proliferation of microstructure of the oxide layer.To compare 12CrMoV alloy steel for high temperature oxidation layer in a load-time and there is no loading time variation of topography.
