spheroidite+

Spheroidite is a steel microstructure that forms when pearlite is heated to below the ___(a)___ temperature for a long time. During the heat treatment, the ___(b)___  structure consisting of layers of ___(c)___  breaks up and forms small spherical globules of ___(d)___ within the ___(e)___ matrix. The small cementite spheres are relatively small with sizes on average of approximately less than __(f)__ micrometers, as can be observed in the micrograph's scale.

Sferoïdiet is 'n staal mikrostruktuur wat gevorm word wanneer perliet lank onder die ___(a)___ temperatuur verhit word. Tydens die hittebehandeling breek die ___(b)___ struktuur bestaande uit lae van ___(c)___ op en vorm klein sferiese bolletjies van ___(d)___ binne die ___(e)___ matriks. Die klein sementiet bolletjies is relatief klein met gemiddelde groottes ongeveer minder as ___(f)___ mikrometer, soos in die mikrograaf se skaal waargeneem kan word.
