摘要: Abstract The investment casting performance of an aviation precision part made from TiB2/A356 aluminum base composite was investigated. According to the function equation between volume fraction TiB2 and thermal-physical property parameters in combination with Pro CAST for secondary development its database, 10% TiB2/A356Al were established. Investment simulation experiment conducted part. results indicate that problems shrinkage porosity defects have been resolved by increasing pouring temperature speed, adding insulation materials around gate riser.
