The surface is a typical brittle and cleavage fracture surface (Figs.
Perfect brittle fracture surfaces shows a typical cleavage fracture necessary for crackable con-rods so as to ensure perfect match of cap and rod and have larger joint surface area than conventional machined smooth surfaces
Investigation of mechanism of cleavage fracture
initiation in intercritically coarse grained heat affected zone of HSLA steel
If a cleavage fracture
is observed in a diamond, it can be important to know if the damage was pre-existing or if perhaps it was introduced after polishing.
Mani also recommends that foundries work with the end user to specify the amount of cleavage fracture
acceptable at a specified low temperature for the grade of iron based on the performance criteria of the casting.
Ostensibly, the propensity for the onset of cleavage fracture
is changed from that of a specimen with a nongrowing crack.
Fractures of the talar body can be further subdivided into three groups 1) cleavage fractures
(horizontal, sagittal, shear, or coronal); 2) talar process or tubercle fractures; and 3) compression fractures.
Pure cleavage fractures
and cleavage combined with depression, followed by type VI [20%] type VI[10%], type V[10%] and type III [5%] respectively.
Several shallow cleavage fractures
were present just under the crystal's surface, oriented in three directions parallel to the rhombohedral faces (Figure 4, left).
