Al–Ti–B grain refiners via powder metallurgy processing of Al/K2TiF6/KBF4 powder blends
Journal of Alloys and Compounds, 2009 Abstract The response to thermal exposure of ball-milled Al/K 2 TiF 6 /KBF 4 powder blends was investigated to explore the potential of PM processing for the manufacture of Al–Ti–B alloys. K 2 TiF 6 starts to be reduced by aluminium as early as 220 °C when ball-milled Al/K 2 TiF 6 /KBF 4 powder blends are heated.

A Study on Thermal Expansion and Thermomechanical Behavior of Composite Metal Foams
Advanced Engineering Materials, EarlyView.The coefficient of thermal expansion of steel–steel composite metal foam (S‐S CMF) is shown to be lower than that of bulk stainless steel while its performance under compression demonstrate excellent mechanical stability and strength at all temperatures with gradualsoftening from 400 to 600 °C.

The Impact of AL-TI-B Grain-Refiners from Different Manufacturers on Wrought AL-alloy
Archives of Metallurgy and Materials, 2019 To investigate the impact of various Al-Ti-B grain-refiners on solidification and grain-refining performance, a wrought aluminium alloy AA6182 was used. Three different grain-refiners from different manufacturers were used to establish the efficiency, i.e. contact time before casting, on the primary solidification and grain formation size.

Microstructure and mechanical properties of an Mg-3Zn- o.5Zr-5HA nanocomposite processed by ECAE [PDF]
, 2014 Mg matrix composites reinforced by natural bone constituent hydroxyapatite (HA) particles have shown promising in-vitro corrosion resistance but are inconsistent in both electrochemical and mechanical performances because of severe particle segregations.
