In particular, for the specimen subjected to 10% prestrain at 196°C, no hydrogen desorption was observed above 280°C.

Relaxation of Shot-Peened Residual Stresses Under

Investigations of the effects of prior room temperature prestrain on creep have been performed in copper 33 , nickel 34,35 , and aluminum 21 . Parker and Wilshire 33 showed that a tensile prestrain of 512.5% changes both the primary and secondary creep rates and that the secondary creep rate decreases with in-creasing levels of prestrain.OASIS Repository @POSTECHLIBRARY: Effect of the amount Postech OASIS Repository.

May 23, 2017 · properties by a compressive prestrain becomes less signicant as the temperature increases. In addition, both yield and compressive strengths of SLBP are found to be highly sensitive to its size while this effect on the modulus and tensile strengths is quite limited.

Influence of carbon on martensitic transformation and effect of the amount and temperature of prestrain on

alloys. Various effects on the alloys, such as annealing temperature, prestrain and deformation temperature, thermal and thermomechanical cycling on the 6 martensitic transformation and the SME are discussed. It is concluded that a high strength matrix and a low stacking fault energy are the essential conditions required to obtain a good shapeHighly Formable Sheet Steels for Automobile through effect of the amount and temperature of prestrain onroom temperature.

Effect of the amount and temperature of prestrain on effect of the amount and temperature of prestrain on

Jun 01, 2017 · In this study the influence of pre-strain on tensile and low cycle fatigue (LCF) resistance were investigated. The amount of pre-strain (=0, 0.2 and 0.4) and pre-straining temperature (203 K490 K) were varied, which resulted in the variation of deformation-induced twin boundaries and fraction of martensite. Tensile tests and fully-reversed strain-controlled fatigue tests were conducted Cited by: 12Publish Year: 2017Author: Seok Weon Song, Jeong Hun Lee, Taekyung Lee, Chong Soo LeeEffect of prestrain on the mechanical properties of effect of the amount and temperature of prestrain onJul 01, 1983 · There was no effect on the transition temperature as the amount of prior strain was increased. Thus, while both dynamic fracture toughness and impact properties can be significantly changed by varying temperature, cold working the material has at best a modest effect on impact energy and then primarily only in the upper shelf region.Cited by: 2Publish Year: 1983Author: M. C. Juhas, I. M. BernsteinEffect of prestrain on microstructure and mechanical effect of the amount and temperature of prestrain onThe effect of prestrain on microstructure and mechanical behavior of aged Ti10V2Fe3Al alloy was investigated. The results showed that prestrain caused the tensile strength to decrease by 5%, but the elongation to fracture significantly improved by about 200%, in comparison with the unstrained samples, using a much shorter aging time.

Effect of prestrain on mechanical recovery in Pu-1 wt % Ga effect of the amount and temperature of prestrain on

Jun 01, 1966 · The recovery of yield stress in a Pu-1 wt % Ga alloy has been studied as a function of prestrain. The specimens were prestrained by either tension or rolling and the kinetics of recovery were studied at 100 and 160° C. The total amount of recovery and the initial rate of recovery were found to be dependent on prestrain and annealing temperature.Cited by: 8Publish Year: 1966Author: I.G. Hanson, J.E. PavlickEffect of prestrain on aging and bake hardening of cold effect of the amount and temperature of prestrain onMar 27, 1998 · In order to establish the effects of prestrain and ambient aging time on the age and subsequent BH, the specimens were prestrained and aged at ambient temperature for various time intervals, and then baked at 170 °C for 20 minutes. In the as-temper-rolled and press-formed condition, the steels were extremely resistant to ambient aging.Effect of irradiation on the stress corrosion cracking effect of the amount and temperature of prestrain onOct 01, 1993 · Effects of irradiation on high temperature SCC and the rapid cracking that occurs during cooldown below 150{degrees}C were characterized.
