the result shows that the steel rolling temperature is the key influence factors of rolling force, and it indicates that the key factor of the stability of rolling process is temperature.By the same time, the reference yield stress of different steel grades are calculated by using the regression...
However, the High Strength Still (HSS) bars (Grades 550, 600, and 700 MPa) resulted in lower TS/YS ratios (less than 1.25) compared with those of Grade 420 MPa. 展开 关键词: TS/YS Ratios HSS DOI: 10.1063/1.5038318 年份: 2018
Hardening and tempering heat-treating process for AISI 4140 will give rise to microstructural change in the steel. Undoubtedly, the difference in yield strength was led mainly by the differential microstructures resulted from the different heat treating parameters used by the heat treatment providers. T...
Theyield strengthor yield point of a material is defined in engineering and materials science as the stress at which a material begins to deform plastically. Prior to the yield point the material will deform elastically and will return to its original shape when the applied stress is removed. ...
This paper describes the steel grades; the influence of grain size, C content, alloying and micro-alloying elements content; the relationships between the ratio and yield strength for plates and pipe. It is pointed out that ratio limitation leads to a chemical composition which can be in ...

Tensile and yield strength. Trend curve is drawn through the averages of the data for individual test temperatures The specified minimum-yield-stress curve is obtained by multiplying the yield trend curve values by the ratio of the specified minimum value, as given in the material specification, ...
In recent years, many studies tried to estimate the yield stress (YS) and ultimate tensile strength (UTS) of metals and alloys without using tensile tests1,2. succeeded in test YS and UTS, for steel alloys only by using a small punch test. Also, Palkovic et al.3 evaluated YS and toug...
The rebar world production has been moving toward higher strength grades during the last decades. For the early nineties there is a British initiative to set a minimum yield strength of 490MPa and weldability conditions for all the rebars to be consumed in England and in several countries of th...
