Effects of solution treatment on room temperature mechanical properties were studied in cast AZ91 (Mg-9%Al-1%Zn-0.2%Mn) and AZ91-0.5%Ca alloys. In as-cast state, the Ca addition contributed to the suppression of discontinuous β phase precipitation a

In this study, we successfully fabricated highly alloyed FeCrMoVC specimens within 2 min by using the spark plasma sintering (SPS) method. The densities of the sintered specimens were almost identical to their theoretical values. Fine (Mo, V)-rich ca

The relationship between the hardness and interlamellar spacing of discontinuous precipitates was investigated for a cast AZ91 (Mg–9%Al–1%Zn–0.3%Mn) alloy. After the specimens were solution-treated at 693 K for 24 h, the specimens were isotherm

This study is intended to investigate the damping capacities of cast Mg-4 pct Zn-(0-0.5) pct Ca biomedical alloys. The Mg-4 pct Zn-(0-0.5) pct Ca alloys had similar damping levels regardless of Ca content in the strain-amplitude-independent region, b

Damping capacities exhibited a decreasing tendency in the order of Mg–8%Zn–2%Al, Mg–6%Zn–4%Al and Mg–9%Al–1%Zn alloys both in the strain-amplitude independent and dependent regions. This is ascribed to the increased values of (Zn+Al) atom

The effects of Sn addition and solution treatment on corrosion behavior were studied in AZ91 magnesium casting alloy. The addition of 5%Sn contributed to the introduction of phase, to the reduction in dendritic cell size and to the increase in the am
