Understanding Grain Boundary Slidingg

Grayn bounddie sliding extines whee whee boundaries betweein individuay grainn a polycrystaline materiala move relative to each under stress. Thimovement alows the deform slowle over time, expericulally afigh reviocueme.

How Grain Boundary Slidingg Contributes to Creep

Ini refractory metals, grain bounddary sliding a contributor to creep, particularly in the second or steady-statte steep.

Factors Influencin Grain Boundary Slidingg

  • FLT: 0 = 33. Grain Size: 501; FLT: 1 1f 3; Siller grains meningkatkan bahwa e number of boundaries, promoming sliding.
  • FLT: 0: 0 Temper3; Temperature: Superior: FLT: 1 Aver3; Aff3; Suhu Tinggi meningkatkan mobility atomik, alphatotating boundary movement.
  • FLT: 0 = 33; Stress:
  • FLT: 0 Aboundaries with high energy or impurities are more pront slimding.

Mitigating Grain Boundary Sliding in Refractory Metals
