The aim of this paper is to characterize welding of AISI 310 austenitic stainless steel to Inconel 657 for use in oil-refining industries. The welds were produced using four types of filler materials; nickel-based alloys designated as Inconel 82, A, 617, and 310 SS. The interfaces and heat-affected zones were characterized by optical and scanning electron microscopy. Interfaces on the two sides...

The mechanical, electrical, and glass transition behaviors (Tg) of polymethylmethacrylate (PMMA)–metal systems have been studied. Considering both the particle size metal filler concentration, electrical conductivity showed a clear dependence on sample thickness to reach percolation. An increase up 400% strain-to-failure for 2% v/v nanometric composites in mechanical test was observed. Tg analy...

The mechanical and thermal behavior of ultra-high molecular weight polyethylene (UHMWPE)/metallic quasicrystal powder (MQP) composites are evaluated at filler volume fractions (∅f) 0.01, 0.02, 0.06 0.15. MQP is based on an aluminum alloy, synthesized characterized to act as a for UHMWPE. preparation the was conducted by compression molding. Morphological analysis reveals larger smaller MPQ part...

Stress magnitude and variability as estimated from large scale finite element (FE) analyses have been associated with compressive strength of human vertebral cancellous cores but these relationships have not been explored for whole vertebral bodies. In this study, the objectives were to investigate the relationship of FE-calculated stress distribution parameters with experimentally determined s...
