Abstract : The mechanical behavior of beryllium as a technological material is reviewed. The potential of beryllium in aerospace structures, in aircraft gas turbines, and in aircraft brakes is briefly discussed. The present state of our understanding of the mechanical behavior of single and polycrystals of beryllium in relationship to the other CPH metals and in terms of dislocation theory is presented. Possible means for improving the low temperature ductility of beryllium are discussed. The role of texture in wrought beryllium products is discussed and also the relationship of the hot shortness of beryllium to the forging problem. Finally, the role of surface defects is considered.
