20. A contribution to the study on cold forging of steel helical gears / Uma contribuição ao estudo do forjamento a frio de engrenagens helicoidais
The forging processes are classified in hot forging, warm forging, and cold forging, that usually provide products that need some further machining operations to achieve manufactured part specifications. Cold forging asks for a special attention when manufacturing complex geometry parts, because its limitation with the forgeability of the workpiece material,

21. AVALIAÃÃO DO REVESTIMENTO A BASE DE LIGA DE NÃQUEL EM AÃO ESTRUTURAL, EMPREGANDO O METAL DE ADIÃÃO ERNiCrMo-3 ATRAVÃS DA SOLDAGEM MIG/MAG / EVALUATE OF NICKEL WELD OVERLAY IN STRUCTURAL STEEL, WITH EMPLOYMENT OF GMAW ERNiCrMo-3 ELECTRODE.
The use of nickel alloy cladding components could be more frequently in petroleum industry. The crescent naphthenic corrosion and high molecular weight of national petroleum contribute for needs of materials with more resistance to corrosion, to temperature and to pressure. At this way, how part of systematic study, this work pretends to define operational r

22. Metodologias para a determinação das propriedades de impacto de baixa energia de laminados metal-fibra / Methodologies to determine low-energy impact properties of fiber-metal laminates
Applications of hybrid fiber-metal laminates include, besides aeronautical industry, the automotive and naval industries. Unlike aeronautical field, impact research activities in the former areas of mobility industry are frequently limited by available laboratory equipment, so that it would be desirable to develop low-cost procedures to determine impact resi
