Modern technological processes make it possible to produce high strength steel with up to 1200MPa yield strength. This high yield strength gives potential ... JDM Costa,JAM Ferreira,LPM Abreu - 《Procedia Engineering》 被引量: 46发表: 2010年 EFFECT OF YIELD STRENGTH ON THE BASIC FATIGUE STRENGT...
yield strength and tensile ductility that surpasses that of conventional 316L steels. High strength is attributed to solidification-enabled cellular structures, low-angle grain boundaries, and dislocations formed during manufacturing, while high uniform elongation correlates to a steady and progressive work-...
Today, based on intensive research anddevelopment efforts high strength steels with yield strengthfrom 460 to 1100 MPa are available for steel structures andcranes. Results from material examinations of the fracture anddeformation behaviour of two steels types, S690 and S890 (EN10137) will be presen...
The subcommittee for Effective Utilization of Yield Strength was established under the Materials Division of the Pressure Vessel Research Committee of the Welding Research Council to study the effects of strain hardening and the yield strength to tensile strength ratio on the various failure modes of ...
2b, we obtained a sample with a negative gradient. In Fig. 2c, we provide the final dimensions of the fatigued samples used in three-point bending tests. The two types of graded sample had the same average yield strength. This average strength was greater than the yield strength of the ...
Regression analysis was used to determine the correlation of the yield strength and the tensile strength to the diamond pyramid hardness values for these steels. Both the yield strength and tensile strength of the steels exhibited a linear correlation with the hardness over the entire range of ...
The study has provided a preliminary characterization of newly developed steels with yield strengths varying from 65 ksi to 120 ksi. On the basis of the preliminary data obtained. it appears that by use of advanced metallurgical processes. high strength steels can be produced which provide ...
The objective of this study is to quantify the effect of hole-making processes and edge-preparation on fatigue performance of ultra high strength steels. A series of fatigue experiments were conducted on steel grades with yield strengths from 700 to 960 MPa using axially loaded coupon samples ...
Upon the addition of Cu both the yield strength and ultimate tensile strength increase markedly, with ductility comparable to that of 0Cu. Extended Data Fig. 2 ADF-STEM analysis of 4Cu, 0Cu and 3Cu annealed at 760 °C for 5 min. a, ADF image (left) of 4Cu showing a high density ...
