Tariq Bhatti 3200113Commercially available two different compositions of(a+β) and lead-tin-brasses were solution treated at 815°C for ½ hr and aged at 400 and 500°C for ½ and 1 hr. The tensile test data were analyzed to find the UTS (ultimate tensile strength), elastic modulus, %elongation and reduction in area. The UTS for (a+β) brass with different heat treatments was found to vary between 371.42 to 417.40 N/mm2 with elongation of 25.7-30.15% and between 474.00 to 619.03 N/mm2 with elongation of 4.60-9.75% for lead-tin-brass. The Rockwell hardness (HRF) with these heat treatments were observed to decrease variably for both (a+β) and lead-tin-brass.]]>Padmavardhani, D. and Y.V.R.K. Prasad,19912229933001Hornbogen, E. and H.
