Preparation of Chromium Silicide Intermetallic Compound Coatings on Austenitic Stainless Steel by Pulsed Electric Current Sintering [PDF]
, 2011 Cr-Si intermetallic compound coatings were coated on an austenitic stainless steel SUS310S substrate by pulsed electriccurrent sintering process to improve its wear and oxidation resistances. The coating was carried out for 0.6-10.8 ks at 1073-1323K at a

Genomic responses to increased temperature and pollinator selection in Brassica rapa L.
New Phytologist, Volume 250, Issue 2, Page 1231-1247, April 2026.Summary Rapid environmental change reshapes both abiotic stress and biotic interactions, yet it remains unclear how these combined forces structure plants' genomic adaptation. In particular, the joint influence of temperature and pollinator identity, two ecological axes undergoing simultaneous global shifts, has rarely been quantified at genomic ...

Jianzhu Gangjiegou Jinzhan, 2023 高强钢在建筑结构中的应用越来越广泛，高强螺栓连接是钢结构常见的连接方式。火灾作用下，高强螺栓的预紧力由于钢材强度退化、热膨胀变形和高温蠕变的影响会发生变化，从而影响连接的抗剪承载力。为探明高强钢连接的高强螺栓预紧力在高温下的变化规律，利用有限元软件ABAQUS建立了单个高强螺栓连接节点模型，分析了螺栓连接在高温下的预紧力变化，采用试验数据进行了验证。进而分析了螺栓规格、连接板厚度、钢材强度和升温速率四种参数对高强螺栓最大预紧力和预紧力完全丧失时温度的影响。分析表明：在ISO-834标准升温下 ...

Macro-dimension effects and phase transformation ofNi-Mn based high temperature shape memory alloys [PDF]
, 2016 Ni-Mn基形状记忆合金是发现比较早的一种高温形状记忆合金，其具有从高温母相（B2）转变为低温四方马氏体的可逆马氏体转变过程。但是Ni-Mn基合金的多晶脆性极大且其形状记忆效应差，因此关于该体系的研究较少。本论文拟通过添加有利于γ相形成的元素（Cu、Co和Fe），促使合金在均质化处理后呈现塑性的fccγ相组织，其后再研究合金在加热和冷却过程中的相转变行为、微观组织结构和尺寸效应，以及在预变形下的高温形状记忆效应。 本文首先以Ni50Mn50为母合金，根据Cu、Co ...

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Cost‐effective and efficient non‐noble‐metal catalysts for selective lignin hydrogenolysis remain elusive, representing a significant challenge in biorefinery. Here, we prepared a nitrogen‐doped carbon supported CoNi bimetallic catalyst, which was successfully derived from zeolitic imidazolate framework (ZIF) via high‐temperature pyrolysis ...

Jianzhu Gangjiegou Jinzhan, 2011 基于火灾高温下空间网格结构的性能,本文根据欧洲规范了中高温下的钢材特性和国际标准升温曲线（ISO834）,对单轴受拉焊接空心球节点高温下的性能进行了数值模拟,分析了空心球的温度场分布规律和极限耐火时间的影响因素。通过分析高温下空心球的应力和位移变化特征,确定了其破坏模式;结果表明钢管根部和赤道处是其高温下受拉承载力的薄弱环节。

High‐Brightness Delayed Imaging Realized by Embedding Zinc Gallate Nanocrystals Into Glass
Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT X‐ray delayed imaging technology leverages an “irradiation‐storage‐thermally stimulated readout” mode, demonstrating unique advantages in intermittent monitoring scenarios such as high‐temperature/high‐radiation environments. This typically requires materials combining abundant carrier‐trapping energy levels with structural thermostability ...
