Evaluation of the performance of α-SiAlON tool when turning Ti-6Al-4V alloy without coolant
(2008-12-01)
Due to their high hardness and wear resistance, Si3N4 based ceramics are one of the most suitable cutting tool materials for machining cast iron, nickel alloys and hardened steels. However, their high degree of brittleness ...
Influence of pouring temperature and alloy additions on the quality of a semisolid material dragged during the continuous-casting strip processing of al-si a413
(2019-01-01)
Al–Si A413 treated and untreated alloys were cast and poured at approximately 720 ºC, 700 ºC, and 680 ºC in a cooling slope to obtain the semisolid material feeding the ceramic nozzle (150 cm 3 ) at the lower roll (single-roll ...
Recycling Al-Si Alloy by Semisolid Material Dragged During Continuous-Casting Strip Processing
(2022-01-01)
Recycled Al–Si (9.2%) alloy contaminated with Fe (0.3%), Pb (3.1%) and Sn (11.4 %) was cast and poured at 650 ºC, approximately 50 ºC above the liquidus line. A cooling slope was used to obtain a semisolid material that ...

Evaluation of strip rolling directly from the semi-solid state
(2006-01-01)
The aim of this work is to study the solidification conditions necessary to produce good quality/low defect metal alloy strip when thixorolling directly from the semi-solid state. To facilitate the study lead/tin alloys ...
