The prediction of the flow stress of an extra-low carbon steel in the two-phase region using continuous cooling curves

Article Abstract:

Continuous cooling curves of an extra-low carbon steel under three cooling rates were measured. The flow stress of the steel was determined in compression tests while the temperature was decreasing. The phase transformation temperatures were established from the cooling rate curve. The latent heat during phase transformation was computed. A new variable, related to the volume fraction of transformation, was defined. Experimental findings indicated that this variable may be described by a quadratic equation.

Impact properties of a laminated composite based on ultrahigh carbon steel and a Ni-Si-steel

Article Abstract:

The impact properties of a laminated composite based on ultrahigh carbon steel and a Ni-Si-steel interleaf material were analyzed using a heat treatment technnique that eliminates carbon diffusion. The miscrostructures of the heated laminated composite specimen was studied using a metallographical approach and a scanning electron microscope. It was found that the notch-impact toughness of the interleaf material affected the ductile-brittle transition temperature of the laminated composite.

Elastic properties of particle-occlusion composites: measurements and modeling

Article Abstract:

A study predicts the effective elastic constants of particle-occlusion composites using phase geometry and the constituent properties. The Mori-Tanaka effective model and the Ledbetter-Datta scattered-plane wave ensemble-average model estimate the macroscopic elastic constants. The study uses acoustic-resonance, pulse-echo and resonance spectroscopy. The applicability of scattered-plane-wave model and the effective-field model to five composites are discussed.
