Howard Jones joined the University from T I Research Laboratories, in 1969, to initiate development of light alloys by rapid solidification and to collaborate with Geoffrey Greenwood on creep behaviour at low stresses. The light alloys work has formed the basis for continuing development of advanced aluminium and magnesium alloys for leading edge applications, led to authorship of the first monograph on Rapid Solidification in 1982 and his former editorship in 1984 of the highly regarded International Journal of Rapid Solidification (now International Journal of Nonequilibrium Processing).

Research Interests

His broader interests include mechanisms and modelling of solidification in general and especially, the mechanism of dendritic and eutectic growth in aluminium, zinc and ferrous alloys. Some of this work has been carried out in collaboration with the Swiss Federal Institute of Technology in Lausanne and the corresponding group at the University of Oxford, and latterly with a new group at the National University of Singapore. He has a longstanding interest in the high temperature behaviour of materials, in particular the stability of microstructure and mechanical properties. Active work is proceeding on the mechanisms of creep at low stresses and intermediate temperatures, on thixoforming of high strength aluminium alloys, and on the role of the matrix in enhancing wear resistance of aluminium-based metal matrix composites reinforced with intermetallic particles. Also, a longstanding interest in the energetics of surfaces and interfaces is being applied to studies of wettability of ceramic by metals, melt infiltration of ceramic preforms and the design of alloys with high resistance to microstructural coarsening.
