However, polymer and ceramic degradable materials exhibit inadequate mechanical properties and their degradation products could cause an inflammatory response [4].
The addition of HA, a constituent of bone, serves to reinforce the MMC and enhance its mechanical properties.
Uniform dispersion of HA is reported to increase the corrosion resistance and mechanical properties of the composites, due to the increase in interfacial area between Mg α-phase and HA particles [3][2].
Factors that affect the degradation behaviour of Mg alloys include: grain size, composition, microstructure and distribution of intermetallic phases.
Assessment of Biodegradable Magnesium Alloys for Enhanced Mechanical and Biocompatible Properties.

Sensitisation towards intergranular corrosion (IC) was achieved by an additional heat treatment at 130 °C with various exposure times and bases on the precipitation of the intermetallic phase Al5Mg8 along the grain boundaries: · Temper O: Material state according to component state: Rolled and soft annealed · Sensitised (17 h/130 °C): Corresponding to material state after planned operating time for components exposed to heat from engines and brakes · Sensitised (500 h/130 °C): Critical condition, commonly not used due to massive IC The different sensitisation states reveal comparable strength properties (elastic limit: 115-120 MPa, maximum tensile strength: 269-271 MPa) as well as similar fatigue strength properties tested in air [1].
No such drop occurs for specimens without mechanical loading for all tempers.
A technical crack with a length exceeding 0.5 mm cannot be observed at the time of the potential drop nor is the specimen stiffness affected at this period of time.
For variation 2, the strain rate was kept constant and the dwell time was reduced by a factor of four.
The reduction of the strain rate by a factor of ten in variation 3 and the same dwell time as for variation 2 reveals fatigue lives comparable to testing under sinusoidal signal form for the soft annealed reference temper while the fatigue life of the critical sensitisation state is enhanced by 20 % compared to testing under variation 2 but still reduced by factor of three compared to testing with sinusoidal wave form.

However, TG data show that Me-SSQ improved the thermal properties of CE greatly.
Introduction Owing to the excellent dielectric properties, mechanical properties, hot/wet resistance and processability, cyanate ester resins (CE) have found wide application in high-frequency numeric printed circuit board (PCB), high-performance wave-transparent structural materials and the structural materials in aero and space fields [1, 2].
The reactivity is a vital factor to determine the curing techniques, even the final properties of materials [19].
Me-SSQ/CE hybrid systems were studied in terms of curing reactivity and thermal properties.
It can be explained by the completely condensed structure and very stable chemical properties of Me-SSQ.

All ensure the required tightness, mechanical strength and microstructure of the joints.
Materials based on intermetallic compounds of nickel and iron with aluminium show unique mechanical properties as well as highstability at elevated temperatures.
This may be attributed to a change of the properties of the steel as a result of its becoming plastic [8] and carburized (graphite moulds) at these temperatures.
When produced under adequate thermodynamic conditions, the NiAl phase was the only constituent of the interlayer; • In joining ceramics with metals by the reactive sintering of intermetallic compounds, it is important that the joining process parameters should be carefully selected so as to take into account the factors that affect the formation of the intermetallic compound (e.g., the stoichiometry of the chemical composition, process temperature) as well as the factors specific for joining these two materials (e.g., temperature, joining time, heating and cooling rates).
