Abstract The flow behavior of a novel Cr-Si alloyed hot stamping steel (Cr-Si steel) at elevated temperature was investigated via isothermal compression tests on Gleeble-3500 thermomechanical simulator with range 600 ~ 900 ℃ and strain rate 0.1~10 s-1. Subsequently, the Arrhenius-type constitutive model, comprising compensation, established in accordance friction adiabatic heating corrected str...

In this paper, the effect of thermomechanical loading on the behavior of deflection-based harvested energies from a shape memory polymer system is experimentally investigated. Samples are created with honeycomb cells from poly-lactic acid using additive manufacturing techniques. The shape memory effect in shape recovery and force recovery paths are studied under thermomechanical tests in bendin...

In this paper, an advanced thermo-mechanical treatment was conducted on AISI 316 austenitic stainless steel. At first, three samples were rolled at the ambient temperature, the temperature of -20 ºC (dry ice and ethanol) and -196 ºC (liquid nitrogen). Then, the samples were annealed at 800 ºC in the time range of 1 to 15 minutes. In each step, the microhardness values of the samples were measur...

A technique is presented for hardening metal products, in particular, the main tools (hammers) and cases of core drilling bits made steel 30HGSA, using thermomechanical surface treatment according to a separate scheme. The method combined laser used study consists use shot peening followed by heat treatment. Its makes it possible increase operational properties their wear corrosion resistance. ...

Heterogeneous microstructures have been proposed to optimize the mechanical properties in respect of strength and ductility synergy many alloy systems. In this work, multi-phase hetero-structured microstructure consisting fine grains coarse where ferrite is embedded vicinity nano-grains was obtained by regulating thermomechanical processing parameters. A yield 1.2 GPa which more than two times ...

AIM To evaluate ex vivo degradation of gutta-percha following six thermoplastic obturation techniques. METHODOLOGY Ninety human-extracted mandibular premolars were selected and divided randomly into nine groups for filling. Group 1: thermomechanical compaction for 3 s with Konne gutta-percha points (Konne Ind. e Com. de Mat. Odontol., Belo Horizonte, MG, Brazil); Group 2: thermomechanical com...
