Aluminum P/M parts can be production sintered in various types of furnaces and atmospheres. Selection of sintering furnace depends upon economic considerations and production rates desired. Batch furnaces have lowest investment costs and are adequate for low to medium production whereas continuous furnaces are more costly but provide higher production rates. strong, well-sintered P/M parts can be obtained in atmos- pheres of nitrogen, dissociated ammonia and in vacuum. Atmos- phere selection depends upon facilities available within individual plants plus property requirements. Highest strengths are produced in nitrogen followed by vacuum and dissociated ammonia. Repro- ducible dimensions can be achieved with proper attention to com- pact density, sintering temperature, dew point and atmosphere. REFERENCES 1. J. H. Dudas and W. A.
