German term or phrase: aK
Just a heading under properties on a specifications table "V-Kerbschlagzähigkeit ak". It's the aK bit I'm unsure about. The property is measured in kJ/m².

English translation:aK
Explanation:
aK = Kerbschlagzähigkeit in Joule/cm²

from ref. below

however, the usual abbreviation is K(index Ic) for the notch impact toughness

oops, KIc is the fracture toughness, sorry.

Anyway, this is the V-notch impact toughness (or Charpy Vee notch CVN)

From a powerpoint presentation (found by google):
Charpy v-notch test apparatus:

The impact toughness is determined from finding the difference in potential energy before and after the hammer has fractured the material. Units are J (Joules) when testing Metals, J/cm2 when testing polymers (Polymers will stretch, metals will snap).

Kerbschlagzähigkeit ak:
ist die Kerbschlagarbeit (AV) dividiert durch den Prüfquerschnitt. Ihre Einheit ist J/cm2.

After examing several documents on this theme, the aK is a German abbreviation and is not used in English texts. Therefore, I\'d just use v-notch impact toughness, (which does not have a common abbreviation, or possibly as CVN, see above) and leave out the aK
