“…thermocouples or resistivity sensors the surface layer must be a thin electrical insulating mechanical protection layer. The tools or rather the sensors surface needs to resist compressive stresses of several tenths of MPa and temperatures of more than 900 °C in oxidative atmosphere [6]. Popular wear resistance layers like AlTiN, TiN, DLC, C-BN, SiC WC either don't have a good stability versus oxidation or don't show good insulation properties at high temperatures.…”

many groups of engineers and researchers worldwide are involved in the application-oriented development of sensors. These efforts are often triggered by industrial applications and their extraordinary requirements in durability and reliability. Typical products are highly specialized sensors e.g. for temperature which are exposed to high physical and chemical stresses like in cutting or forming processes. One promising approach of space resolved or surface sensitive measurements is the use of thin film sensors. A key factor for the successful use is an insulating wear resistance layer on top of the sensor. In this report a well-known hard layer made from aluminum oxide was optimized under mechanical and electrical aspects.

“…The numbers of these parts in the automotive sector have seen an exponential increase in recent years. [1] As the process is continuously being developed and enhanced, designers are continuing to come up with ever more complex and intricate parts, which are difficult to produce using exisiting technologies. [2] Additional requirements are also emerging for reducing the sheet thickness in these parts to around 1 millimetre.…”

“…It is well known that the properties of the so‐called advanced high‐strength steels (AHSS) can be substantially varied by thermal and mechanical treatments during the processing . Some of these steels, such as bake‐hardening steels, air‐hardening, and the press‐hardening steel grades, only attain their strength properties by forming and/or heat treatment or by hot forming with simultaneous quenching . For press‐hardening from temperatures above A c 3 , large plastic forming potential exists in the austenitic state.…”

Modified press‐hardening processes are very attractive for manufacturing safety‐relevant vehicle body parts from steels with martensitic–ferritic microstructures. In the process developed, the formation of the two‐phase microstructure and the hot sheet forming simultaneously occur subsequently to an intercritical annealing. By contrast, previously used process chains do not integrate setting of a multi‐phase microstructure within the forming step. In order to successfully combine the intercritical annealing with the actual forming, comprehensive knowledge of the microstructural evolution and the resulting mechanical properties is needed. Specifically, different heat‐treating routes are used to obtain different microstructures of ferritic–martensitic dual‐phase steels and partial martensitic steels. As a result of intercritical annealing in the temperature range of Ac1–Ac3, it is possible to vary the martensite volume fractions from 7 to 96 vol%. The data obtained can be employed for numerically describing the microstructural transformation and for designing the heat treatment process. It is demonstrated that this combined process allows for designing steels that feature properties that are similar to complex‐phase steels.
