Deformation behaviour of A356, Al-11Si-2.5Cu-0.6Fe, and Al-18Si-2.5Cu-0.6Fe alloys forged under different processing conditions

Khemraj; Jha, A.K.; Ojha, S.N. (Inderscience Publishers, 2019)

The present paper aims to investigate the feasibility of bulk processing of Al-Si alloys under different processing temperatures. Three different compositions of Al-Si alloys (namely A356, Al-11Si-2.5Cu-0.6Fe, and ...
Microstructure and electrical conductivity of Al-SiCp composites produced by spray forming process

Srivastava, V.C.; Ojha, S.N. (Indian Academy of Sciences, 2005-04)

Al-SiCp composites have been synthesized by spray forming process with variation in particle flow rate, size of reinforcement particles and their volume fraction. The microstructure of composites and their electrical ...
Microstructure and wear characteristics of an Al-4Cu-20Pb alloy produced by spray deposition

Ojha, S.N.; Pandey, O.P.; Kumar, M.; Ramachandra, C.; Tripathi, B. (1992)

Al–4Cu–20Pb alloy was spray deposited at a gas pressure of 1.4 MPa and melt flow rate of 1.6 kg min−1. The microstructure of the preform exhibited equiaxed morphology with grain size varying from 20–25 μm. Uniform distribution ...
