The Effect of Tempering Temperature on the Microstructure and Properties of a Novel High-Temperature Bearing Steel. [PDF]
The microstructure, precipitation behavior, and mechanical properties of an ultrahigh-strength stainless bearing steel after tempering were investigated using multiscale characterization techniques along with tensile and impact testing. Based on the experimental results, strengthening and toughening mechanisms are discussed.

High-Temperature Tempered Martensite Embrittlement in Quenched-and-Tempered Offshore Steels [PDF]
Embrittlement induced by high-temperature tempering was investigated in two quenched-and-tempered offshore steels. Electron backscattering diffraction and analysis of Kernel average misorientation were applied to study the coalescence of martensite; transmission Kikuchi diffraction coupled with compositional mapping was used to characterize the ...

Association of mortality with high temperatures in a temperate climate: England and Wales [PDF]
Background It is well known that high ambient temperatures are associated with increased mortality, even in temperate climates, but some important details are unclear. In particular, how heat–mortality associations (for example, slopes and thresholds) vary by climate has previously been considered only qualitatively.

Effect of high temperature tempering on the phase composition and structure of steelmaking slag
Abstract Blast furnace slag and steelmaking slag, as the main accessory products of iron and steel smelting, are piled up in large quantities due to their huge output, high treatment difficulty and low comprehensive utilization rate, which has a serious impact on the land and environment.

Effects of High-Temperature Tempering on Mechanical Properties and Microstructure of SA738 Gr.B Steel [PDF]
In this paper, JMatPro thermodynamic software, OM, SEM, TEM, and EPMA were used to study the microstructure and mechanical properties of SA738 Gr.B nuclear power steel after tempering at 630–710 °C. When tempered within the range of 630–670 °C, a huge amount of M3C and MC carbides were dispersed and precipitated in the ferrite matrix, and the strength ...

Dynamic and High Temperature Quasi-static Examination of Tempered Glass
Abstract In everyday use glass materials cause a lot of damage or injuries when broken, as fracture mechanism and damage runoff cannot be predicted precisely. To gain knowledge on this issue, we studied the properties of tempered glass.
