Strain Rate Effect on Tensile Behavior for a High Specific Strength Steel: From Quasi-Static to Intermediate Strain Rates
The strain rate effect on the tensile behaviors of a high specific strength steel (HSSS) with dual-phase microstructure has been investigated. The yield strength, the ultimate strength and the tensile toughness were all observed to increase with increasing strain rates at the range of 0.0006 to 56/s, rendering this HSSS as an excellent candidate for an energy absorber in the automobile industry...
متن کاملSLOW STRAIN RATE TESTING OF STEEL 14MoV6-3
Slow strain rate test (SSRT) represent a dynamic slowly increasing strain imposed by an external means on uniaxial tension specimen according to ASTM G 129 standard. It is used for relatively rapid screening or comparative evaluation of environmental, processing or metallurgical variables that can affect resistance of material. Testing has been accomplished on low-alloyed boiler steel 14MoV6-3 ...
متن کاملOn the negative strain rate sensitivity of Hadfield steel
The digital image correlation (DIC) technique was utilized in conjunction with mechanical experiments carried out at different strain rates to study the negative strain rate sensitivity (NSRS) in face-centered cubic (fcc) Hadfield steels. The results shed light onto the variation of local strain fields and serrations in the stress– strain curves of Hadfield steels as a function of strain rate w...
متن کاملHot Tensile and Fracture Behavior of 35CrMo Steel at Elevated Temperature and Strain Rate
To better understand the tensile deformation and fracture behavior of 35CrMo steel during hot processing, uniaxial tensile tests at elevated temperatures and strain rates were performed. Effects of deformation condition on the flow behavior, strain rate sensitivity, microstructure transformation, and fracture characteristic were characterized and discussed. The results indicated that the flow s...
متن کاملDynamic tensile test and specimen design of auto-body steel sheet at the intermediate strain rate
In this paper, the tensile testing method at the intermediate strain rate is established and tensile tests of steel sheets for an auto-body have been performed to evaluate dynamic material properties. A high speed tensile testing machine has been developed for tensile tests at the intermediate strain rate. A simple jig fixture for gripping a specimen has been designed to diminish the load ringi...
