Question

Explain difference between primary and secondary texture.

Answer 1

Differences between primary and secondary textur are as follows :

• The primary texture happens before the melt cools.

• The secondary structure happens after the melt has cooled.

• The primary texture refers to the roughness of a surface. The secondary texture refers to the waviness of a surface.

• The roughness and waviness are the two imperfections found between the primary and secondary texture.

• The primary texture includes transverse feed marks and irregularities within them.

• The secondary texture caused by vibrations, and hear treatment.
