To improve crash worthiness and fuel economy, the automotive industry is using increasingly Advanced High Strength Steels (AHSS). Forming AHSS often causes lubricant film break down and galling that increases scrap rates and tool maintenance cost. This book introduces a model developed to predict the severity of galling for given lubricants, die materials and coatings in forming galvanized AHSS. Finite Element Analysis (FEA) and various experiments were conducted to develop a galling prediction model. The prediction model considered the empirical relationships between galling and important tri...
