2015; Vansteelandt et al. 2006). Even though there is a vast literature covering transitions in SRH, there are few covering more than one country at a time and, importantly, even fewer consider possible biases due to non-ignorable dropout. The main objectives of this study were to ...
The precipitation process in a wrought PH13-8 steel during ageing was investigated using a position sensitive atom probe. The precipitates formed are enriched in Ni and Al, and depleted of Fe and Cr, yet the composition is far from the stoichiometric NiAl phase. They may take on different sh...
321 stainless steelThe heat affected zone (HAZ) of stabilised austenitic stainless steel welds may exhibit a serious form of intercrystalline cracking during service at high temperature. This type of embrittlement, well known as stress relief cracking, is related to thermal ageing: a fine and ...
Changes in the morphology of precipitates in VM12 steel have been shown in the form of diagrams. The research aim was to analyze the precipitation processes. The tests were performed on VM12 steel in the as-received condition (after heat treatment) and after 5000 hours of ageing at the ...
Thermal insulation cover have three to six layers, liner is high silica glass fiber cloth, stainless steel braided cloth, ceramic fiber cloth, glass fiber cloth or high-SI aluminum cloth, and insulating layer is ceramic or glass fiber or aerogel blanket, and the prote...

aprepare quesions in a funnel sequence then another list of quesions in an inverted funnel sequence. 准备问题在漏斗序列然后问题另一张名单在一个被倒置的漏斗序列。[translate] aPM 304L and 316L stainless steel have been compacted at 400, 600 and 800 MPa and sintered in vacuum and in nitrogen–...
High-Mn austenitic steel is expected to be a next-generation structural material for cryogenic use by maintaining a stable fcc crystal structure even at cryogenic temperature by adding a large amount of C and Mn which are γ-stabilizing elements. In some cases, Cr is added together with C as...
This paper presents results of the quantitative measurement of the size of MX precipitates, subgrain size and dislocation density in a P91 steel that had been creep tested for 113,431 h at 600 °C. The same measurements were conducted in the same P91 steel in the as received conditions. ...
