Adolf Martens (Adolf Karl Gottfried Martens), 6 March 1850 in
Gammelin – 24 July 1914 in
Groß-Lichterfelde, was a German
metallurgist
Metallurgy is a domain of materials science and engineering that studies the physical and chemical behavior of metallic elements, their inter-metallic compounds, and their mixtures, which are known as alloys.
Metallurgy encompasses both the sc ...
and the namesake of the
steel structure
martensite
Martensite is a very hard form of steel crystalline structure. It is named after German metallurgist Adolf Martens. By analogy the term can also refer to any crystal structure that is formed by diffusionless transformation.

and the martensitic transformation, a type of
diffusionless phase transition
In chemistry, thermodynamics, and other related fields, a phase transition (or phase change) is the physical process of transition between one state of a medium and another. Commonly the term is used to refer to changes among the basic states o ...

He also made significant contributions to the field of
tribology
Tribology is the science and engineering of interacting surfaces in relative motion. It includes the study and application of the principles of friction, lubrication and wear. Tribology is highly interdisciplinary, drawing on many academic f ...
. The functional relationship between the coefficient of friction and the product of sliding speed and viscosity divided by the normal load (well known as the
Stribeck curve) was experimentally explored by Adolf Martens in 1888, long before
Richard Stribeck Richard Stribeck (7. July 1861 in Stuttgart , † 29. March 1950) was a German engineer, after whom the Stribeck Curve is named.
