【Abstract】 The influence of isothermic quenching heat threatment on structure andproperties of throwing paddle made from hypoeutectic white cast iron havestudied. The result obtained has shown that the impact toughness, the wearresistance and the working life of the throwing paddle have been markedlyincreased after it has been subjected isothermic quenching. There fore thistechnique has greater technical and economical significance.更多还原
