In order to optimize the strength-toughness matching of auto body components. Taking B1500HS steel as research object. The influence die temperature on microstructure and properties was studied by hot stamping tests flat die, mechanical observation tests. study shows that is not sensitive below 250°C. When 20–250°C, tensile strength above 1400 MPa, while plastic-toughness poor; 300°C, begins ge...

thermoplastic starch (tps) materials present several advantages to the plastic industry andwhen blended with other materials they can exhibit improved mechanical and moisturesensitivity properties compared to pure tps materials. further investigations on tps: pvablends are of particular interest due to their excellent compatibility and improved properties suchas tensile strength, elongation, to...

Neural network predictions suggested that strength of a high strength steel weld metal with 7 wt. % nickel and 0.5 wt. % manganese could be increased significantly at moderate expense to impact toughness by additions of carbon. Based on this, three experimental weld metals were produced with carbon levels between 0.03 and 0.11 wt. %. Mechanical test results were in agreement with predictions. W...

Eucalyptus regnans was subjected to thermal treatment. The samples were placed in superheated vapors at 120, 130, 140, 150, 160, 170, 180, 190, and 200 °C at ambient pressure to determine the effect of heat treatment on the physical-mechanical properties of Eucalyptus regnans. The results showed that heat treatment played an important role in the impact toughness, nail-holding ability, surface ...

Nowadays, Ni-free austenitic stainless steels are being developed rapidly and high price of nickel is one of the most important motivations for this development. At present research a new FeCrMn steel was designed and produced based on Fe-Cr-Mn-C system. Comparative studies on microstructure and high temperature mechanical properties of  new steel and AISI 316 steel were done. The results ...

Bioglass-graphene oxide composites can be served as a high-potential candidate for biomedical applications due to its specific mechanical properties. In this study, the 45S5 bioactive glass (BG) - graphene oxide (GO) composite containing 2 wt. % GO was coated on titanium alloy via electrophoretic deposition process (EPD). The synthesized GO was incorporated into BG coating to improve the mechan...
