This phenomenon could be due to the fact that both techniques utilize chemically reactive materials.
Mixture materials that require heating give out higher concentration as well as greater amount of CO2.
This avoids the need for heated materials and ensures CO2 level will remain low.

Experimental set-up Machine and materials.
The materials used during the experiments are: St37-2, St52-3 and St52-LQ.
Based on tests for different material-thickness combinations, both parameters proved to be correlated.

The sharp increase in the impact value of the specimens after PWHT is believed to be due to the comprehensive effect of softening of the materials [11], grain growth, and so on.
This might be because bulk material was used; another reason may be that additional phases in steel can be seen by XRD only if they amount to more than 5% of the material [12].

Tunable ferroelectric materials are one of the candidates that are considered for use in these applications.
Barium titanate (BaTiO3) based ceramics are prospective candidates of dielectric materials in the application of capacitors and tunable microwave devices [5, 6].
Recently, barium zirconate titanate (BaZrxTi1-xO3) materials have been attracted for making dynamic random access memories (DRAM) and tunable dielectric devices, just above the Curie temperature in their paraelectric state [9].
Typically, Thornton model was developed to describe the growth of sputtered materials in dependence of two parameters, substrate temperature and sputter pressure [22-23].

Introduction Single-crystal CaF2 is a material with very excellent optical properties [1].
This means that strain rate has great influence on the strength of the material.

Introduction Laser material welding of aluminum alloys is working together or replacing conventional manufacturing processes in an increasing number of industrial applications.
The investigated material was the AA5083-H111 alloy (ISO AlMg4.5Mn), the mechanical properties of which are reported in Table 1.
The maximum value of the UTS ratio was 90% of the base material with porosity content less than 3%
