Effect of Hot Rolling on Grain Refining Performance of Al–5Ti–1B Master Alloy on Hot Tearing on Al–7Si–3Cu Alloy
Rathi, Sachin Kumar; Sharma, Ashok; Di Sabatino Lundberg, Marisa (Journal article; Peer reviewed, 2018)It has been known experimentally that TiAl3 acts as a powerful nucleant for the solidification of aluminum from the melt; however, a full microscopic understanding is still lacking. To improve microscopic understanding, ... -
Influence of Annealing of Al-5Ti-1B Master Alloy on Hot Tearing of Cast Al-7Si-3Cu Alloy
Rathi, Sachin Kumar; Sharma, Ashok; Di Sabatino Lundberg, Marisa (Journal article; Peer reviewed, 2017)Hot tearing is a common and severe defect encountered in aluminium alloys castings. It is affected by alloy composition as well as processing conditions and variables. In Al–7Si-3Cu presence of copper increases mechanical ... -
Performance of Al-5Ti-1B master alloy after ball milling on minimizing hot tearing in Al-7Si-3Cu alloy
Rathi, Sachin Kumar; Sharma, Ashok; Di Sabatino Lundberg, Marisa (Journal article; Peer reviewed, 2017)Hot tearing of Al–7Si–3Cu alloys with addition of as received Al–5Ti–1B grain refiner and ball milled grain refiner have been studied with constrained mould casting to investigate the effect of these additions on hot tear ...
