Historical Evolution of theWave Resource and Energy Production off the Chilean Coast over the 20th Century
(MDPI, 2018-09)
The wave energy resource in the Chilean coast shows particularly profitable characteristics for wave energy production, with relatively high mean wave power and low inter-annual resource variability. This combination is ...
The Influence of Thermal History on the Multistage Transformation of NiTi Shape-Memory Alloys
(MDPI, 2018-04)
The multistage martensitic phase transformation of a polycrystalline NiTi shape-memory alloy (50.3 at. %Ni-49.7 at. % Ti) has been studied by means of calorimetric measurements. After a conventional thermal treatment ...
On the Influence of Infra-Red Sensor in the Accurate Estimation of Grinding Temperatures
(MDPI, 2018-11-26)
Workpiece rejection originated by thermal damage is of great concern in high added-value industries, such as automotive or aerospace. Surface temperature control is vital to avoid this kind of damage. Difficulties in ...
