Mechanical Engineering and Material Science Review

Vocabulary practice flashcards covering mechanical engineering tolerance fields, aluminum alloy designations, precipitation hardening processes, and structural load vulnerabilities.

Dimension $d$ (Toleranzfeld einer Bohrung)

The lower deviation (unteres Abmaß) in the tolerance zone diagram of a bore relative to the zero line (Nulllinie).

Number $1$ in the designation Al Cu4Mg1

Represents the magnesium content in percent (Magnesium-Gehalt in Prozent, $1\%$).

Number $4$ in the designation Al Cu4Mg1

Represents the copper content in percent (Kupfer-Gehalt in Prozent, $4\%$).

Age Hardening (Aushärten)

A precipitation strengthening process for certain light-metal alloys achieved through solution heat treatment, quenching, and aging (Lösungsglühen, Abschrecken und Auslagern).

Buckling / Compression (Druck / Knickung)

The mechanical stress type that is the most damaging and critical for long workpieces with small thickness (lange Werkstücke mit geringer Dicke).

Tolerance Zone (Toleranzfeld)

The range defined between the upper deviation (oberes Abmaß) and lower deviation (unteres Abmaß) relative to the nominal size (Nennmaß) and zero line (Nulllinie).
